It looks like you have some HTTP code on the same lines as the data you are trying to graph. Look at your rrd dump. The data column name is fontsize.
The data being sent must have absolutely no other text on the line, except description=value or description : value
Hope it helps.
Cheers Vernon

Hi All,
I am unable to display custom graph into xymon page. Only following figure(graph-tag) shown in inside trends column and inside xymon KPI(custom) page:
I am using “xymon-4.2.3”.
I am trying to display custom graph.
(1) I have “SlabInfo.sh” file which display following two values into xymon page:
SLAB Info: inode_cache : 831040
dentry_cache : 20268144
(2) In "hobbitserver.cfg" file I added(red marked) at the end:
TEST2RRD="cpu=la,disk,inode . . . . . . . . . . . . . . ,temp=devmon,SlabInfo=ncv"
GRAPHS="la,disk,inode, . . . . . . . . . . . . . . . . . ,temp,SlabInfo"
(3) In "hobbitgraph.cfg" file I added following lines:
[SlabInfo]
TITLE Slab inf
YAXIS Bytes
DEF:inode=SlabInfo.rrd:inode_cache:AVERAGE
DEF:dentry=SlabInfo.rrd:dentry_cache:AVERAGE
LINE2:inode#00CCCC:Inode cache
LINE2:dentry#FF0000:Dentry cache
COMMENT:\n
GPRINT:inode:LAST:Inode cache \: %5.1lf%s (cur)
GPRINT:inode:MAX: \: %5.1lf%s (max)
GPRINT:inode:MIN: \: %5.1lf%s (min)
GPRINT:inode:AVERAGE: \: %5.1lf%s (avg)\n
GPRINT:dentry:LAST:Dentry cache\: %5.1lf%s (cur)
GPRINT:dentry:MAX: \: %5.1lf%s (max)
GPRINT:dentry:MIN: \: %5.1lf%s (min)
GPRINT:dentry:AVERAGE: \: %5.1lf%s (avg)\n
(4) Rrd dump output is:
